These aerial images of the Poquoson Flats in lower Chesapeake Bay show the clear decline of eelgrass cover between 1990 (L) and 2010 (R). Note the near total disappearance of eelgrass from the deeper offshore waters and the consequent shoreward contraction of the eelgrass meadows. The images were collected as part of the annual Seagrass Monitoring and Assessment Program at the Virginia Institute of Marine Science (VIMS).
